• The upgrade steps appear to be using incorrect CLI syntax. Elsewhere in the docs, updating the CLI is aspire update --self, and updating packages/projects is aspire update (there’s no documented aspire update project). Please align these commands with the aspire update reference and Upgrade Aspire guidance.

The easiest way to upgrade to Aspire 13.3 is using the `aspire update` command:

<Steps>

1. Update the Aspire CLI:

   ```bash
   aspire update

1. Update your projects:

   aspire update project

**src/frontend/src/content/docs/whats-new/aspire-13-3.mdx:84**
* This sample also references `builder` without defining it, which makes the snippet non-runnable as written. Please add the builder creation line (or include enough context) so the example is complete.

var nsp = builder.AddNetworkSecurityPerimeter("my-nsp")
    .WithAccessRule(new AzureNspAccessRule
    {

This code sample uses builder without showing where it’s created (for example, DistributedApplication.CreateBuilder(args)). Since this is a standalone snippet in What's New, consider making it self-contained so readers can copy/paste it.
